From what I have read since the original post, the game was developed by Iga, the same guy who had worked on Symphony of the Night and Lament of Innocence. So, it is by a former Konami employee who had a deep history with the Castlevania series, but came into it after the NES era. Bloodstained Ritual has been on my radar for a long time, but the extremely lengthy development time has left me with lowered expectations.
